SMPTE ST 2020-1 – Format of Audio Metadata and Description of the Asynchronous Serial Bitstream Transport

This Standard defines the basic structure and timing requirements of an asynchronous serial audio metadatastream with respect to an associated video signal. These requirements apply to the serial metadata streamseither present on asynchronous serial data communications links between devices or present in the verticalancillary (VANC) data packets transported by the video signal. The Standard also defines the Data ID (DID)and Secondary Data ID (SDID) values used to identify the VANC packets themselves and to associate themetadata in VANC packets with specific audio programs.

Associated Standards SMPTE 2020-2 and SMPTE 2020-3 define two methods of mapping the metadata intoancillary data packets.
